There are MANY of us who do, some more affected than others. It’s had many names over the centuries: shell-shock; combat fatigue; thousand-yard stare and so forth, but it’s been a part of combat and war since war began.
Mostly it’s what we do to ourselves rather than to others; only VERY rarely will it flow over onto others. Part of it can be how we respond to our spouses, to authority (especially overbearing, self-appointed authoritarians, like liberals or IRS agents or BATFags or drug cops or so-called big government “conservatives” of the type often found here on FR) figures. For the most part we internalize it, we isolate and we have a real hard time with relationships. Over time this does take a toll and we do have a high suicide rate.
I hope today you are feeling well and strong.
